Φ1000mm giant oil pipe processing lathe has been upgraded! Solving the industry problem of thick-walled welding groove accuracy

Apr 10, 2025

For the industry pain point of thick-walled welding groove accuracy, this upgrade has achieved a dual improvement in processing accuracy and efficiency through core technology breakthroughs and process optimization. The following are the specific upgrade contents and solutions:

1. Core upgrade technology: Solving the problem of thick-walled welding groove accuracy

High-precision spindle system
Dynamic balancing technology: Using high-precision dynamic balancing correction, the spindle radial runout is ≤0.01mm, ensuring that the groove angle deviation is ≤±0.5° when processing thick-walled pipes (wall thickness ≥50mm).
Rigidity enhancement design: The spindle box adopts an integrated casting structure, and the vibration resistance is improved by 30%, avoiding vibration deformation in thick-walled pipe processing.
Intelligent groove processing module
Three-dimensional profiling: integrated laser ranging and closed-loop feedback system, real-time correction of tool path, groove surface roughness Ra≤3.2μm.
Multi-axis linkage control: supports X/Y/Z/C four-axis linkage, can process V-shaped, U-shaped, double V-shaped and other complex grooves, angle range 0°-60°.
Special clamp for thick-walled pipes
Hydraulic self-centering chuck: intelligent adjustment of clamping force, suitable for Φ800-Φ1200mm pipe diameter, eccentricity error ≤0.05mm.
Auxiliary support device: For long pipe (≥12m) processing, add floating support to reduce the influence of deflection.

2. Comparison of solutions to industry problems

Problem Type Traditional Solution Pain Points Upgraded Solution Advantages
Groove Angle Deviation Manual adjustment is inefficient, with a deviation of ±2°-3° Closed-loop control + automatic compensation, with a deviation of ≤±0.5°
Poor Surface Quality Vibration causes ripples and burrs High-rigidity structure + low-speed precision cutting, Ra≤3.2μm
Low Processing Efficiency Single-piece cycle as long as 48 hours Multi-axis linkage + automation, cycle reduced to 18 hours

3. Upgrade value and industry impact

Precision improvement: groove accuracy reaches the international API 5L standard, reducing welding defect rate by more than 90%.
Cost reduction: processing efficiency increased by 60%, and energy consumption per piece reduced by 25%.
Application expansion: can cover high-strength steel pipe processing such as X80 and X100, meeting high-end needs such as deep-sea oil and gas and polar engineering.

4. User case verification

After a large pipeline company applied the upgraded lathe:
Processing accuracy: groove angle deviation decreased from ±1.8° to ±0.3°;
Welding pass rate: increased from 82% to 98%;
Unit cost: reduced by 15%, annual cost savings of more than 5 million yuan.
